If you want to save some troubles have you ever tried considering Firefox?
And by your question... I would go in the settings and restore IE7 to the defaults (erasing everything and making it to the same as when you got your computer)
I just upgraded to IE 7 and now every time I open the program it takes me to a screen for customizing my settings. When I click to save my settings it says that saving my settings failed. My question is how do I get rid of this screen and just have IE load my homepage?
